Serial No. 651,339.

To all whom it may concern:

Be it known that I, GEORGE J. J UNKER, a citizen of the United States, and a resident of Mount Vernon, in the county of Jeflerson and State of Illinois, have invented a new and Improved Violin, of which the following is a full, clear, and exact description.

The invention relates to stringed musical instruments of the viol type, such as violins, cellos, bass viols, etc.

The object of the invention is to provide a new and improved violin arranged to produce a rich and deep tone, to permit convenient fingering of the strings, and to maintain the strings in tune for a long period without requiring retuning.

For the purpose mentioned use is made of a hollow body having approximately parallel sides or sound boards, and means connected with the said parallel sides and the strings to cause the sides to vibrate.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the violin; Fig. 2 is an enlarged longitudinal central section of the same; Fig. 3 is a similar view of the same on the line 3-3 of Fig. 4; Fig. 4 is an enlarged cross section of the same on the line 4-1 of Fig. 2; Fig. 5 is a side elevation of the tail end of the body with the chin rest in position thereon; and Fig. 6 is a cross section of the same on the line 66 of Fig. 5.

The hollow body A of the stringed musi cal instrument consists essentially of parallel sides A, A a bottom A a top A and ends A, A, of which the end A is connected with the neck B terminating in the head or scroll C, provided with the usual means for holding one end of the strings D extending over the finger-board B and over the bridge E to connect with the tail piece F attached in the usual manner to the button G secured to the end A of the hollow body A.

The legs E of the bridge E are seated on the upper ends of two vibratory bars H and I, of which the bar H is short in comparison to the bar I, and the said bar H is pivoted at its lower end on a block J, glued or otherwise fastened to the inner face of the side A of the hollow body A, and the said bar H is also pivoted on a block K, glued or otherwise fastened to the under side of the top A of the hollow body A. The bar I is connected at its lower outwardly-bent end I with the lower portion of the side A and the said bar I is also attached to a block L secured to the inner face of the side A approximately opposite the block J, as will be readily understood by reference to Fig. 4, and the upper ends of the bars H and I extend unobstructedly through openings A formed in the top A of the hollow body A. Now by the arrangement described the sound producer consisting of the strings D stretched over the bridge E is in contact with the vibratory bars H and I, which in turn are attached to the sides A and A which latter form two sound boards and receive the pressure of the stretched strings D in a vertical direction so as to insure a free vibration. It will further be noticed that by attaching the short and long vibratory bars H and I to the sides A and A in the manner described horizontal vibration of the bridge E will cause the sides A and A to vibrate. It has been found that the sides A and A are caused to vibrate together but in opposite directions to each other, and that such vibration causes a smooth and pure tone of increased volume.

By providing the hollow body A with parallel sides A, A it is evident that the player can readily finger the strings D on the finger-board B as the parallel sides do not obstruct the forward or backward movement of the hand manipulating the strings D on the finger-board B. In order to render the body A as large as possible the middle portion of the bottom A is bent or swelled in a downward direction, as plainly indicated in the drawings. The hollow body A is preferably provided at the side A with the usual S-shaped sound holes A shown in Figs. 1 and 3.

The tail end of the side A is provided exteriorly with a cushion L of felt or a like material and with headed pins N adapted to be engaged by slots 0 formed in an attaching flange O of a plate 0 extending transversely and provided on the top with an angular forwardly-extending flange O to which is fastened a chin rest P. The plate 0 is also provided at the bottom with a flange 0 having a downward and forward extension 0 for supporting the shoulder pad. The slots 0 are preferably enlarged at their upper ends to readily pass over the heads of the pins N when placing the chin rest in position on the body A or removing it therefrom.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A stringed musical instrument of the class described, comprising a hollow body provided with an apertured top and approximately parallel sides, vibratory bars attached to the inner faces of the said sides, one of the said bars being long and the other short and both extending through the openings in the top of the said body, a bridge having connection with the upper ends of the said vibratory bars and strings supported by the bridge.

2. A stringed musical instrument of the class described, comprising a hollow body provided with an apertured top and approximately parallel sides, blocks attached to the inner faces of the said sides, a block attached to the under side of the top of the said body, a short and a long vibratory bar, the long bar being secured at its lower end to the lower portion of one of the sides of the body and to the block on the said side, and the said short bar being pivoted on the block 011 the other side and on the said block on the top of the body, the upper ends of the said bars extending through openings in the top of the body, a bridge having connection with the upper ends of the said vibratory bars the strings supported by the bridge.

3. A stringed musical instrument of the class described, comprising a hollow body provided with an apertured top and approximately parallel sides, blocks attached to the inner faces of the said sides, a block attached to the under side of the top of said body, a short and a. long vibratory bar, the long bar being secured at its lower end to the lower portion of one of the sides of the body and to the block on the said side, and the said short bar being pivoted on the block 45 on the other side and on the said block on the top of the body, the upper ends of the said bars extending through openings in the top of the body, strings, and a bridge over which pass the strings and having its legs seated on the upper ends of the said vibratory bars.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE JACOB JUNKER.
